WAGON-BRAKE.

Specification of Letters Patent.

Patented Sept. 11, 1906.

Application filed May 8,1905. Serial No. 259,369.

bridge City, in the county of Wayne and State of Indiana, have inventedcertain new and useful Improvements in Wagon-Brakes, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

This invention relates to improvements in brakes for wagons; and itconsists in a novel mechanism for applying the brakes and retaining themin contact with the wheel or wheels of the wagon or what is commonlyknown as maintaining the'brakes set, and will be hereinafter more fullydescribed in the specification and particularly pointed out in theclaim.

The Object of this-invention is to provide a brake mechanism that isreadily applied to wagons or other vehicles, which mechanism may beoperated by a shoe-brake lever situated at either side of the frontportion of the wagon adjacent to the driver and in such position on thewagon as to be easily accessible by the driver and that will be morepowerful than the ordinary lever-brake power; also, to provide abrake-operating mechanism that will remain set and maintain the brakesin their set position or in contact with the wheels until released bythe operator. I at- Y tain these objects by means of the mechanismillustrated in the accompanying drawings, in which similar numerals ofreference designate like parts throughout the several views. 'l

Figure 1 is a'longitudinal sectional elevational view of a wagon,showing my invention of a brake mechanism applied thereto. Fig. 2 is adetail enlarged inverted plan view of the brake-gearing, and Fig. 3 is asimilar inverted detail elevational view looking in the direction of thearrow a. (See Fig 2.)

An open wagon 1 is carried by suitable forward wheels 2 and rear wheels3, mounted on their supporting-axes 4 and 5. The brakeshoes 6 may be ofany suitable formsecured on. the ends of the brake-beams 7. Brakehangers8, whereby the brake-beams 7 are suspended, depend from the brake-hangerwhich latter are secured to the longitudinal side sills 10 of the wagon.Situated underneath the body of the wagon at' a point in advance of therear wheels 3 is a cross-beam 11, which extends transversely across andalong the bottom of the wagon and is secured at its ends to the sidesills 10. At a point intermediate .the ends of the .brake-beams 7 issecured a clevis 12, to which the rear end of the brake-rod 13 ishingedly connected, and the forward end of said rod is connected to thebrake-operating mechanism, which I will now proceed to describe.

Double-bearing pedestals 14, provided with the bearings 15 and 16, aresecured to the bottom side of the cross-beam 11 in such position thereonthat when the crankshaft 17 is placed in its bearings 16 the crank 18will fall in the proper plane to engage the bend 19, formed on theforward end of the brakerod 13.

The brake-shaft 20 extends entirely across the bottom of the wagon andhas its ends supported in hangers 22, which latter are secured to thebottom side of the sills 10 and are provided to support the prolonged oroverhanging ends of said shaft. T heends of the brake-shaft 20, thatproject beyond said hangers 22, are preferably provided with the squareends 23 to receive the square eyes of the operating-levers 24, whichlevers are removably secured on the ends of said shaft, so that thebrakes-may be operated from either side of the 'wagon whether theoperator be on the wagon or on the ground.

A mutilated or segmental gear 25 is secured on that portion of the shaft2() situated between the pair of bearings 15 of the pedestals 14, andthe said mutilated gear is arranged to. mesh or engage with thecrankshaft gear 26, which latter is secured on thecrank-shaft 17 to turnthe latter.

When the operator desires to apply the brakes, all that is necessary tobe done is to pull the brake-lever 24 in the direction of the arrow b torevolve the crank 1S in the direction of the arrow c until it contactswith the stop-plate 27, at which position, it will be observed onreferring to Fig. 3, the center of the brake-rod 13 is in alinement, ornearly so, with the center of the crank andthe center of the shaft 17;.In other words, the crank 18 is on a dead-center, so that'the brake-rod13 has no influence over it to cause it to rotate yin the reversedirection to release the brakeshoes 6. The brake-shoe mechanism istherefore locked in position to maintain the brakes set. When the brakesare thus set, it will be IOO readily seen that they cannot be releaseduntil the operator moves the lever 24 in the directipn opposed to thatindicated by the arrow The pedestal-bearings 14 are provided with theremovable caps 28 for the purpose of readily removing the shafts 17 and20 when so desired,l which ca s are secured to their pedestals 14 byIsuita le bolts.

The overhanging stop-plate 27 is held in position intermediate thebearings 15 and 16 on that pedestal situated nearest the crank 18 inposition thereon to contact with the end of said crank when the latteris moved in the position illustrated in Fig. 3.

Having thus fully described this my invention, what I claim as new anduseful, and desire to cover by Letters Patent of the United Statestherefor, is-

In a wagon-brake, the combination with a wagon mounted on suitablewheels, brakehangers de ending from the body of said wagon, bra e-shoescarried by said hangers,

longer or brake shaft, a gear on said crankshaft meshing with saidmutilated gear, and "a crank-shaft plate situated in a plane directlyabove said crank, so that, when the crank has passed above its center tocontact with said stop-plate and thereby become locked said brake-shoeswill beretained in contact with the wagon-wheels to lock them. Intestimony whereof I afliX my signature in presence of two Witnesses.
